Are there any libphp4* files inside the /apps/local/apache_test_Ali/libexec/ directory?

Yes.
I have one libphp4.so.4.2.3 and one libphp4.3.2

and a symbolic link libphp4.so on one of these library.
When I switch to libphp4.2.3 (comipled exactly with the same configure options). I can run Apache correctly.

But is not the case with the 4.3.2

Please try using this CVS snapshot:

  http://snaps.php.net/php4-STABLE-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php4-win32-STABLE-latest.zip

As you suggest, I try the http://snaps.php.net/php4-STABLE-latest.tar.gz

Unfortunatly the problem seem to be the same !

Cannot load /apps/local/apache_test_Ali/libexec/libphp4.so into server: dlopen: /apps/local/apache_test_Ali/libexec/libphp4.so: No such file or directory


I have also to remove the external gd (2.0.7) library from my configure. I got an undefined symbol for gdFreeFontCache.

I don't know if AIX has 'ldd' command, but if it does,
what does 'ldd libphp4.so' output?

It seems that ldd on AIX does not work correctly.
However, the output is:

ldd libphp4.so
libphp4.so: No such file or directory

We use the dump command on AIX. The output is.

dump -H libphp4.so 

libphp4.so:

Get the latest stable CVS snapshot and try this configure line:

./configure  \
  --prefix=/apps/local/php-4.3.2/ \
  --disable-all \
  --with-apxs=/apps/local/apache_test_Ali/bin/apxs \
  --with-pdflib=/apps/local/apache_test_Ali/lib/pdf 

As you suggset, I try your configure command.
Unfortunatly the result is the same !

ie:

Cannot load /apps/local/apache_test_Ali/libexec/libphp4.so into server: dlopen: /apps/local/apache_test_Ali/libexec/libphp4.so: No such file or directory

Add --disable-cli to that configure line. See also bug #25058
(it's for apache2 but pretty much same issue, AIX too)

I add --disable-cli as you suggest. But the problem is the same.

Starting WWW-Server apache.
Syntax error on line 67 of /apps/local/apache_test_Ali/conf/httpd.conf.kplus20:
Cannot load /apps/local/apache_test_Ali/libexec/libphp4.so into server: dlopen: /apps/local/apache_test_Ali/libexec/libphp4.so: No such file or directory

Did you do 'rm config.cache' and 'make clean' before that?
Also, did you read all the comments in bug #25058?
Especially the part about copying the libphp4.so manually..

Yes I do.
Before any compilation, I do a make distclean.

Concerning the comments on bug #25058. I read it, but I did'nt see any particular point. 

I just copy de libphp4.so into my libexec directory. As I done it for the 4.2.3 version

Well, did it work when you manually copied the file?
(even without the --disable-cli maybe?)

When I use the following configure commad, and copy manually the compiled library, everything is OK and Apache run normally.

#!/bin/sh


exec configure \
  --prefix /apps/local/php-4.3.2/ \
  --disable-all \
  --disable-cli \
  --with apxs=/apps/local/apache_test_Ali/bin/apxs

When I add the pdf 

 --with-pdflib=/apps/local/apache_test_Ali/lib/pdf

Apache cannot run !!

Cannot load /apps/local/apache_test_Ali/libexec/libphp4.so into server:
dlopen: /apps/local/apache_test_Ali/libexec/libphp4.so: No such file or
directory

This is not the case with the 4.2.3 version.

Please try using this CVS snapshot:

  http://snaps.php.net/php4-STABLE-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php4-win32-STABLE-latest.zip

And this time try with your normal configure line for PHP.
I don't think 'make install' will work yet, but you shouldn't need --disable-cli anymore.

I download the recommanded version.
I should add to my configure command

--disable-cli
--without-pear

And now when I try to run Apache, I obtain:

./apache[23]: 58706 Illegal instruction

It seems to be a core dumped for Apache.
When I remove LoadModule php4 from my httpd.conf everything
seems to be ok and Apache run normally.

The problem is resolved now.
I download the 4.3.3 available on the web Site and compile it with gcc version 3.2.3.

With this verison of gcc when you include the PDFLib you have to put the libgcc_s.a in one of the directory figuring in the output of dump -H on libphp4.so

Everything is OK now.
Thanks to all for your participation.
